Natural sound
When you keep the sound, it is stretched without changing the pitch, so voices don't sound too high or too deep. At very high or very low speeds you may prefer to remove the sound.
How it works
Kingdom of Files re-encodes the video to MP4 (H.264) on your device. The media engine (about 32 MB) is downloaded only once, and your video is never uploaded.
Frequently asked questions
Which speeds are available?
From 0.25x (four times slower) to 4x (four times faster).
Is the sound kept?
Yes, with a natural pitch. You can also remove it.
Does slow motion look smooth?
Each frame is shown longer, so very slow speeds can look less smooth if the original has few frames per second.
Can I change the speed of several videos?
Yes. Select multiple files at once.
Is my video uploaded?
No. It is processed in your browser.
Is there a watermark?
No.
